Anthropic Launches Claude Sonnet 5 & Brings Back Fable 5 — What You Need to Know
It’s been a massive week in AI. On July 1, Anthropic dropped not one but two major announcements: the return of Claude Fable 5 after a government-mandated pause, and the launch of Claude Sonnet 5 — a new mid-tier model that punches way above its weight class. If you’re a developer, a power user, or just someone who relies on AI for daily work, these updates matter.
What Happened?
| Model | Status | Availability | Key Detail |
|---|---|---|---|
| Claude Fable 5 | ✅ Restored (July 1) | Pro, Max, Team, Enterprise | 50% weekly limit until July 7, then usage credits |
| Claude Sonnet 5 | 🆕 New Launch | Default for Free & Pro, also Max/Team/Enterprise | Intro pricing: $2/M input, $10/M output through Aug 31 |

The Fable 5 Comeback
Remember when the U.S. Department of Commerce hit Claude Fable 5 with export controls on June 12? After weeks of negotiations, those controls were lifted on June 30, and Fable 5 began rolling back globally on July 1. For users on Pro, Max, Team, and Enterprise plans, Fable 5 is back at 50% of weekly usage limits through July 7. After that, it switches to a credits-based system.
Access via AWS, Google Cloud, and Microsoft Azure Foundry is being restored as quickly as possible.
Claude Sonnet 5 — The Real Story
While Fable 5 returns, Sonnet 5 is more consequential. It scores 63.2% on agentic coding benchmarks (Opus 4.8: 69.2%, Sonnet 4.6: 58.1%) and slightly outperforms Opus 4.8 on knowledge work. Introductory API pricing: $2/M input, $10/M output through Aug 31, then $3/M and $15/M.
California Signs Largest Gov’t AI Deal
Gov. Newsom announced Claude is now available to all state agencies, cities, and counties at 50% off with free training. Also: a $15M cyber defense program. First use cases include DMV wait times and Medicaid optimization.
